condensation

I have a single window about 3ft square, in the living room of an old farmhouse. It's a hinged single-glass paned "door" and nearly airtight. I framed out a plexi panel about 6 inches behind it for insulation purposes and that's pretty tight too. Lots of moisture gathers on the inside of the plexi with no moisture on the "interior" paned door. Is there a way to prevent all that moisture inside the "pocket" I created. The only real issue with it is that we frequently can't see through it. Thanks.

I'll give it a look. The inside paned window is a tightly hinged door and the plexiglas I installed last week those 6 inches away is glued to a frame I made with tight tolerances and crack/peal weatherstripping along all the edges. It's that outside "window" I'd much rather loosen up and am guessing it's on the upper side I ought to do it as that's where it's protected from the northeast elements where I'm located. Perhaps removing the weatherstripping along the top side will do it. Anyway, thanks for the tip. Much appreciated!
